With the Nintendo3DS debuting imminently, you might be wondering why glasses-free 3D is being limited to handheld devices when it’s just begging to come to the living room. The reason is simple: glasses-free 3D is easy to do when you can predict where someone’s eyes are going to be, but much less so the more viable viewing angles there are. So while it’s easy for Nintendo to predict where a user’s eyes are going to be on a handheld device that they will need to clutch with both hands during playtime, the problem becomes a lot more difficult when you’re talking about a 60-inch HDTV viewable from any angle in a living room.

Samsung‘s working on that problem, though. They’ve just showed off a 55-inch 3D LCD TV that is completely glasses-free, and it could revolutionize three-dimensions in our living rooms if it’s ever released.

While glasses-free 3DTVs have been shown off before, what really sets Samsung’s 55-incher apart is the sheer number of viewpoints that are supported. You’ll be able to get glasses-free 3D as long as you’re sitting at up to nine different angles in front of it, which is the best we’ve seen yet.

How does it work? The TV is equipped with an LCD panel whose optical refraction index can be changed in front of an LCD panel used for displaying images. The first LCD panel functions as a lens and shows different images to the right and left eyes. If the optical refraction index isn’t changed, you see 2D: if it is, you see 3D.

Other specs look impressive too: it’s full HD at 1080p, has a brighness of 500cd/m2 and a static contrast ratio of 4,000:1.

Unfortunately, this HDTV is a prototype right now, and it’ll take about three years to commercialize the tech. But glasses-free 3D in 2015 is just going to rock, don’t you think?
